Answer:
Frogs are amphibians, they can live both on land and in water. Their lives begin in water when they are eggs. From the eggs, tadpoles emerge, which also live in water. When these tadpoles fully develop they begin to live on land.
A frog is a poikilotherm, which means that it is a cold-blooded animal. The body temperature is not constant and varies according to their surrounding environment. So, when it is very cold, they lay in the sun to get warmer and when it is very hot, they get into the water bodies to cool themselves.
The habitat of a frog is quite varied and can be found all over the world, except maybe, of course, the Antarctic region. They are not marine animals. They can be found only in freshwater habitat. A frog goes into summer sleep called aestivation and winter sleep called hibernation, to escape the peak summer and winter conditions. The common Indian frog goes by the scientific name, Rana tigrina.
